Description

BURGULAR ALARM SYSTEM

 

This is basically an anti theft alarm system which can help us to detect the person around our house, building or office. This project uses PIR sensor for detecting the unknown person who enters our house. It detects within its range and start beeping the buzzer, to give us alert. 

PIR SENSOR

 

Passive Infrared sensor detects the radiation which emits from the heat of the body, it can be either from the human or animal body. 

 

CONNECTION
